Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD8351ARM is determined by strict equivalence across electrical performance and mechanical compatibility parameters. The primary substitute identified is the AD8351ARMZ, which maintains identical electrical specifications including frequency response, gain, P1dB compression point, supply voltage range, and current consumption. Both parts utilize the same 10-MSOP package footprint and surface mount technology, ensuring mechanical and thermal compatibility on existing PCB layouts.

The substitution logic is based on the following critical parameters:

• Frequency range: 0Hz ~ 2.2GHz (identical)
• Gain: 26dB (identical)
• P1dB: 14.6dBm (identical)
• Supply voltage: 3V ~ 5.5V (identical)
• Supply current: 28mA ~ 32mA (identical)
• Package: 10-MSOP (identical)
• Mounting: Surface Mount (identical)

Parameter Comparison

Engineering Selection Recommendations

The AD8351ARMZ is the direct functional equivalent of the AD8351ARM. Selection of the AD8351ARMZ is supported by its active product status with Analog Devices Inc., ensuring continued availability and manufacturing support. The AD8351ARMZ carries ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements for new designs and production systems.

The transition from AD8351ARM to AD8351ARMZ involves no electrical performance degradation or functional compromise. Both devices are pin-compatible and footprint-compatible, requiring no circuit redesign or PCB layout modification. The primary distinction is packaging format: AD8351ARM is supplied on reel, while AD8351ARMZ is supplied in tube format.

Frequently Asked Questions (FAQ)

Q: Can AD8351ARMZ directly replace AD8351ARM in existing designs?

A: Yes. The AD8351ARMZ is electrically and mechanically identical to the AD8351ARM. No circuit modifications, PCB layout changes, or firmware updates are required. Both devices operate identically across the specified frequency range, gain, and power supply parameters.

Q: What is the difference between AD8351ARM and AD8351ARMZ?

A: The devices are functionally equivalent with identical electrical specifications. The primary differences are product status (AD8351ARM is obsolete; AD8351ARMZ is active) and packaging format (reel versus tube). AD8351ARMZ includes ROHS3 compliance and REACH unaffected certification.

Q: Are there any package or footprint differences?

A: No. Both parts use the 10-MSOP package with 0.118" width (3.00mm). PCB footprints are identical, and no layout modifications are necessary for substitution.

Q: What supply voltage range is supported?

A: Both AD8351ARM and AD8351ARMZ operate from 3V to 5.5V supply voltage. Ensure your power supply design accommodates this range for proper device operation.

Q: Is the AD8351ARMZ suitable for new production designs?

A: Yes. The AD8351ARMZ carries active product status and current regulatory compliance (ROHS3, REACH unaffected), making it appropriate for new designs and ongoing production.
